INSTALLATION
Continued
WARNING: Failure to position
the parts in accordance with these
diagrams or failure to use only
parts specifically approved with
this heater may result in property
damage or personal injury.
INSTALLING LOGS
It is very important to install the logs exactly
as instructed. Do not modify logs. Only use
logs supplied with heater.
1. Place bottom log (#1) on grate to fit as
illustrated in Figure 18. Make sure open
areas of log set line up with burner ports
(see Figure 19). Log will fit securely
on chassis.
IMPORTANT:
Make sure
log does not cover any burner ports.
2. Facing front of unit, place top log (#2)
onto the pegs in the center of the bot-
tom log (see Figure 20).
3. Position log piece (#3) by aligning
holes on underside with remaining pegs
on bottom log (see Figure 21).
4. Place lava rock around base of heater.
CAUTION: After installation
and periodically thereafter, check
to ensure that no flame comes in
contact with any log. With the
heater set to High, check to see if
flames contact any log. If so, re-
position logs according to the
log installation instructions in this
manual. Flames contacting logs
will create soot.
